Replace part of expression without killing the rest of it

I had a page element that was used in zillions of expressions in various workflows. Now due to design reasons I have to replace it with something else. But when I try to change the relevant expressions, it kills off the rest of each of them. Some of them are pretty complex, so rewriting them from scratch is a drag to say the least. I wish there would be a way to change a part of an expression without the remainder being removed.


I referred to the “current project” as “the project of this and that group”. Now I don’t want to have that group anymore, so I want to use instead something like “Current user’s Current project.” Bad luck I guess.
